Answer: Significant figures are important to show the precision of your answer. This is important in science and engineering because no measuring device can make a measurement with 100% precision. Using Significant figures allows the scientist to know how precise the answer is, or how much uncertainty there is.
Explanation:
Answer:
0.00701 moles of neon gas will occupy 170 ml of volume under the same conditions.
Explanation:
The relationship of number of moles and volume at constant temperature and pressure was given by Avogadro's law. This law states that volume is directly proportional to number of moles at constant temperature and pressure.
The equation used to calculate number of moles is given by:
where,
are the initial volume and number of moles
are the final volume and number of moles
We are given:
Putting values in above equation, we get:
0.00701 moles of neon gas will occupy 170 ml of volume under the same conditions.
Answer:
When silver nitrate (AgNO3) and potassium chloride (KCl) combine in their liquid state, they form two products by double displacement method.
Silver Chloride (AgCl) and Potassium Nitrate (KNO3)
The reaction is AgNO3 + KCl --- AgCl + KNO3
The precipitate formed is AgCl
